COMBINED OIL TANK AND MEASUREV SPECIFICATION forming part of LettersPatent No. 420,402, dated January 28, 1890.

Application filed August 16, 1889, Serial No.320,926- (No model.)

.of Nebraska, have invented certain new and useful Improvements inOil-Tanks; and I do hereby declare that the following is a full, clear,and exact description of theinvention, which will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in oil tanks or vessels, theobject being the production of a tank which will purify and measure theoil, and which will be inexpensive and durable and efficient for thepurpose intended.

The invention consists of a tank having a measuring-vessel communicatingtherewith; further, in a tank having a cylinder therein provided with astrainer for removing the impurities from the oil, a piston working inthe cylinder, and a measuring-vessel communicating with the cylinder toreceive and measure the oil, and, finally,-the invention consists in thenovel construction, combination, and adaptation of parts, substantiallyas hereinafter described 'and specifically claimed.

In the accompanying drawings, forming part of this specification and inwhich like letter of reference indicate corresponding parts, Figure 1represents a perspective view of a tank embodying my invention. Fig. 2represents a similar view thereof, partly broken away to disclose theinterior construction and arrangement; and Figure 3 represents asectional View of the pumping apparatus.

Referring by letter to the. drawings, A designates the tank,which isconstructed of suitable material, of cylindrical form, with a depressionB on one side thereof. The top of the tank is formed with a depressionO, and in said depression the hinged cover D is placed. The purpose forproviding the de pression O is to prevent oil from spilling over theouter surface of the tank.

Communicating with the bottom of the tank is a cylinder E, in whichworks a piston or plunger F, having a valve G therein, and the handle orrod H of the piston extends upward through the top of the tank to be inreach of the attendant or user. In the cylinder is placed a strainer. Jfor removing impurities or foreign matter from the oil before it entersthe cylinder.

K designates a pipe leading from the cylinder to a vessel L, arranged inthe depressed side of the tank, said vessel being provided with agraduated scale M and a discharge spout or cook N. In the pipe K is avalve K, which opens on the downstroke of the piston to allow the oil topass into said pipe and closes on the upstroke of the piston to preventthe oil returning to the tank.

The operation of my invention will be readily understood from theforegoing description, taken in connection with the drawings, and is asfollows: The oil is placed in the tank at the top thereof and flows intothe cylinder at the bottom of the tank, the strainer in the cylinderremoving foreign matter from the oil The piston is elevated, the valveupon the elevation of the piston opens, and the oil descends to thebottom of the cylinder. The piston is then depressed, forcing the oilthrough the pipe to the measuring-vessel, in which the desired quantityof oil is measured and discharged by the spout or cook. The sidedepression in the tank receives the measuringvessel, and the same isthereby prevented from contact with any outside object.

It is evident that I provide a simple and inexpensive tank in which anyquantity of oil may be measured in a rapid and perfect manner, and bymeans of which the oil is rendered pure.

Having thus described my invention, what I claim as new, and desire tosecure byLetters 'Patent, is

and a strainer in one end, a plunger in the cylinder, having a valvetherein, a pipe leadmy ownI have hereunto aflixed my signature ing' fromthe lower portion of the cylinder in presence of tWo Witnesses. to a topof the tank, and the measuring-vessel arranged in the depression in theside of ELOF BENSON. the tank and having said pipe entering it,\Vitnesses: all substantially as described. R. DODD,

In testimony that I claim the foregoing as A. PEARSON.
